Nordic neighbours release new advice on surviving war

Exceptionally well-armed NATO + JEF members, and Finland well within distance to use conventional artillery to turn St Petersburg to rubble. This is a public-awareness and support-building exercise rather than a real concern. This is like the RAF frequently issuing press-releases about intercepting Russian jets.

Uh..

If we turn St Petersburg into rubble, I doubt anyone will be worrying about a few trifling conventional weapons. NATO and Russia go at it, and we're all just sitting around next month waiting for the Chinese, Brazilians, Indians and South Africans to sort out who is responsible for which relief efforts.

Actually, now I think about it, that quad will probably be far more concerned with determining the disposition of the remaining NATO/Russian warheads. So even relief efforts might be impacted by their more pressing concerns.

In any case, the world would just be a mess for a good long while.

NATO and Russia go at it and everyone is screwed, there will be no winners, nobody on the sidelines, no picking through the spoils.

Despite what Hollywood would have you believe, there would be nations that survive a NATO/Russia war. Namely, any nation in the Southern Hemisphere not called Australia or New Zealand. Mother Nature's winds and Father Physic's half lives combine to give unaligned southern hemisphere nations the break of a lifetime. (Or of a species' lifetime I guess?)

All that said, you are absolutely right about "spoils". No one is gonna be thinking about "spoils". Probably top of everyone's list of questions will be, "How many warheads are left? And what remnants of NATO or Russia control them?"

We're talking about two groups who would have conclusively shown they are perfectly willing to use their nuclear arsenals to achieve their goals. That, combined with the fact that their goals would become a whole lot less lofty overnight makes me think the world would become a very precarious place.

That's an old assumption. Modern modelling shows that the southern hemisphere gets it's share from the northern hemisphere relatively fast. Only the shortest lived isotopes won't make it down there. Then there is the dust/smoke/black carbon to consider. If there is much, that will make it down there, too. Causing weather weirdness, misharvests, and so on.
